CHARLES OOLAHAN, OF CLEVELAND, OHIO.

CbRD-HOLDER FOR GRAIN-BINDERS.

SPECIPICATZQEQ forming part of Letters Patent No. 308,062, datedNovember 18, 1884.

Application filed June 27, 1883. (Mullet) To all whom it may concern.-

Be it known that I, CHARLES COLAHAN, of Cleveland, Cuyahoga county,Ohio, have invented certain new and useful Improvements in Cord -Holdersfor Automatic Grain-Binders, of which the following is a specification,having reference to the accompanying drawings.

My invention relates to cord holders for modern grain binders, and isparticularly adapted to the so-called Appleby Binder.

My invention consists in the construction and arrangement of parts foroperating the cord-holding disk, as hereinafter described, andparticularly pointed out in the claims.

The object of my invention is to simplify the construction of suchdevices and decrease their cost,while at thesame time their durabilityis increased and they are less liable to get out of order.

In the drawings, Figure l is a plan or inner side view of a portion of abinder showing my improvement. Fig. 2 is a view of the opposite side ofthe same. Fig. 3 is a detail view showing the holder, the intermediatewheels, and a portion of the side of the knotter-driving wheel with thewedge-shaped projecting tooth; and Fig. 4 is a detail view showing aportion of the rim of the wheel wilh the inclined tooth and theintermediate gear-wheel.

A is a plate or bracket outside of the usual breast-plate and carried bythe binder-shaft A, which is suitably supported on the frame of thebinder. Upon this shaft is secured the cam and gear wheel A.

B is the knotter or tying-bill, pivoted on the plate A and provided withpinion b. The wheel A is provided with segment-gear a, which engageswith the pinion I) at the proper time to rotate the tying-bill. So farthe parts do not differ materially from those in an ordinary machine ofthe Appleby type.

E is the usual notched holding-dislgwhich, co-operating with the usualspringpressed grooved jaw or clamping-plate, F, holds the end of thebinding-cord which leads from the binder-arm. (Not shown.) Theholding-disk is provided with the pinion D, and thespringpawl e preventsthe disk from rotating backward.-

G is a gearwheel meshing with the pinion 0 D and secured to or formingpart of the gearwheel 0. The teeth of the latter wheel are of ellipticalform, as shown, or, if desired, they may be of angular form. These teethare engaged at the proper time by the wedge-shaped 55 projection ortooth c, secured in an inclined or spiral direction on the periphery orrim of the cam and gear wheel A. By this means the holding-dsk E isintermittingly moved or partially rotated the distance from one notch 6Qto the next at each revolution of the cam and gear wheel A, and it isretained in position by the spring-pawl e.

It will be observed that the holdingdisk is rotated in adirectionopposite to thatin which 6 the cord-holding disk E. provided with the 7pinion D, and the intermediate gear-wheels, C C, substantially as andfor the purpose set forth.

2. The combination of the tying-bill, the

gear and cam wheel A, the inclined tooth c 80 on the periphery of saidwheel, the intermediate gear-wheels, the holdingdisk E, and the yieldingholder-plate F, located at the side of said disk opposite the cam andgear wheel,substantially as and for the purpose set forth.

In testimony whereof I have hereuntosubscribed my name.

CHAS. COLAHAN.
